Answer #1

answer :

A. the wavelengths emitted by fluorescence are always longer the the wavelengths absorbed in the excitation.

explantion:

absorbed energy > emitted energy in any cases. because some of light utlized by compound

absorbed wave length < emitted wave length because energy and wave length always inversly proportional

    true/false 1. Energy of absorbed photon equals energy of emitted photon. 2. Following emission, molecule returns to its lowest energy state by a series of rapid vibrational relaxations. 3. The lifetime of the excited vibrational states is about a femtosecond; the lifetime of the excited electronic state is generally longer than a nanosecond. 4. Photon absorption usually occurs when a molecule is in its ground electronic state.
